Definitions
- the invention relates to a device for solar thermal gasification of carbonaceous feedstock comprising a solar reactor with at least one, preferably a plurality of translucent window (s) for the introduction of concentrated solar radiation and a gasification chamber with a preferably rectangular bottom and receiving means for the feedstock.
- the solar thermal gasification of carbonaceous feedstock serves the thermal decomposition of various starting materials under a controlled atmosphere for the production of a synthesis gas and is described, for example, in CH 692927 A5, WO 2008/027980 A1 or the article by P. v. Chem. Zedtwitz, A. Steinfeld: "The solar thermal gasification of coal - energy convergence efficiency and C0 2 mitigation potential" in Energy 28 (2.003) 441-456.
- Characteristic of solar thermal gasification is that radiation energy of an external source, preferably concentrated solar energy is used to produce the process heat required for the gasification reaction.
- the quality of the synthesis gas obtained is of course essentially determined by the ratio H 2 to CO and by the ratio C0 2 to CO.
- the shift of the ratio H 2 to CO can be achieved at temperatures of 250 to 450 ° C in a particularly simple manner with water vapor (water gas shift). Otherwise, the option exists to gasify with a mixture of H 2 0 and C0 2 and thus influence the ratio of H 2 to CO.
- Coal, biomass and various carbonaceous waste materials, such as contaminated soils, sewage sludge, filter residues and the like, have been proposed as feedstock for solar thermal gasification.
- Carbon-containing wastes are often used as low-grade secondary fuels for the operation of clinker or cement kilns.
- the use of such lower-grade fuels is associated with a number of disadvantages.
- the replacement of high quality leads Coal due to lower-grade fuels leads to a decrease in the adiabatic flame temperature in the sintering zone or main firing of 2300 ° C. to temperatures below 1900 ° C., with significant disadvantages in the clinker process already being observed at temperatures below 2100 ° C.
- a decrease in the flame temperature by 200 to 300 ° C by using low-grade fuels and in particular by using alternative fuels leads to a less favorable temperature profile over the longitudinal axis of the rotary kiln and usually leads to the ideal over a short range extending temperature maximum on a extends longer range at a lower temperature.
- the observed reduction in the quality of the clinker primarily affects the clinker reactivity.
- Fluidized bed reactors are unsuitable for particulate materials, their use would therefore require a large crushing effort. They are also eliminated for large capacities for design reasons, so that constructions with a stationary material bed must be used. In particular, there is the requirement to distribute the feedstock while minimizing the bed height on the largest possible area and to find ways to feed the reactor in a simple manner and in the shortest possible time with material and then discharge the ash just as easily and quickly.
- the present invention therefore aims to develop a device of the type mentioned in that the above requirements are taken into account.

- the at least one drawer has a height between the bottom and the upper edge of the side walls of less than 50 cm, in particular less than 40 cm.
- the material bed may be at most 35 cm thick to ensure that the material is gasified over the entire layer thickness on the same day. If the layer thickness is too high, there may also be the risk that an insulating ash layer is formed on the upper side of the material bed, which prevents gasification of the underlying residual quantity.
- the at least one drawer is movably arranged, this can be pushed out of the solar reactor in a simple manner and pushed into this again.
- the material loading and unloading can take place outside the solar reactor or outside the gasification chamber, so that loading and unloading together with operating personnel must penetrate into the because of the low height poorly accessible and also laden with hot and toxic atmosphere gasification chamber ,
- the configuration is devised preferred in this context that the at least one deposition drawer between a loading located outside of the gasification chamber and Entla 'and a working position located in the gasification chamber is slidable.

- a loading and unloading building is preferably arranged on both sides of the solar reactor, in which the drawers for taking the loading and unloading position are displaced.
- each portal-like cross-loading and / or unloading devices are arranged, which are movable in the longitudinal direction of the drawers.
- the loading and unloading buildings are closed buildings so that the interior of the buildings can be controlled in terms of temperature conditions and atmospheric gas composition. This allows a controlled cooling of pushed out of the gasification chamber drawers and a controlled ventilation or ventilation of the building in order to deduct the possibly emerging from the ash gases.

- the solar reactor above the gasification chamber has a further chamber, in which the concentrated solar radiation enters through the at least one translucent window.
- the concentrated solar radiation thus does not get directly into the gasification chamber, but in the mentioned further chamber.
- the direct irradiation in the further Chamber is observed there an immediate increase in temperature, wherein the heat transfer takes place in the gasification chamber through the ceiling of the gasification chamber.
- the gasification chamber and the further chamber are separated from one another by a blanket composed of high-temperature-resistant panels.
- the high-temperature resistant plates act here as radiation elements or radiation plates which radiate the thermal energy into the gasification chamber.
- the said plates are usually available only in defined dimensions or can not be made arbitrarily large, with a corresponding support structure should be provided.
- a support structure for the high-temperature resistant plates is provided, comprising supporting means for supporting the support structure, which are arranged between the drawers.
- the support means in this case comprise at the bottom of the gasification chamber between the drawers extending, at a distance from the ceiling terminating partitions.
- the support means preferably comprise support columns supporting the partitions and carrying the support structure.
- the radiation plates separating the gasification chamber from the further chamber are therefore preferably made of graphite, preferably with a SiC coating.
- the support columns are preferably made of SiC (silicon carbide).
- the drawers can be made of steel and covered with a suitable refractory material. In order to be able to push the at least one drawer back and forth between the working position and the loading and unloading position, a closable opening is preferably provided on two opposite sides of the solar reactor.

- the drawers are shown in an empty condition and it can be seen that the bottom of the drawers have a variety of Has openings 33 in the form of a hole pattern through which the water vapor and / or the carbon dioxide gas can escape from the distribution chamber 15.
- the bottom of the drawers carries a grid-like subdivision 31, which forms a plurality of shallow trays for receiving the gravel bed 14.
